OK, so I can’t post ads to s.s.b-b. Where CAN I post them?

Looking for a kinky partner? Try posting your personal ad in alt.personals.bondage or alt.personals.fetish.
Looking to buy or sell some stuff? Try posting in alt.sex.marketplace or alt.sex.erotica.marketplace.
Hmm, that sort of covers it for starters! (What am I forgetting, loyal readers?)
